MACHINE'FoR MAKING PAPER Boxes.

Speciiication forming part of Letters Patent No. 12,51 l, dated March13. 1855.

nails',tacks,spice, dac.; and I dol hereby declare that the following isafull, clear,v and Y exact descriptionofthe constructionv and opieration of the same, referencekbeing -had to the annexed drawings,making part of this specification, in which- Figure'l is a longitudinalside elevation,`

Fig. 2 is a top view, Fig. 3 a front view and part section at the 'lineIII and II," and Fig. 4. a back end View, of the machine.

The nature of my invention'yconsists in an .arrangementfof rollers tolbring-the paper from an endless roll along the machine to the placewhere the box is to be m,a de seondly, in astamporknite frame by whichthe paper is cut into the lrequired shape necessary for" folding;thirdly, in a pasting-frame provided with suitable paste-boxes soarranged. as to paste those parts of the paper necessary to be pasted;fo urthly, in a wheel provided with arms` to Vwhich molds are attached,around which' the boxes are to be made; itthly, in an arrangement ofslides by which the paper is folded `around the mold,land,' sixthly, ina 'pairlot pinchers to draw off the box from the inold after completion.These different parts are made to move successively partly together andpartly one after the other, said motions being produced by anarrangementof levers. actuated by cams or toes fast upon shafts and working in sucha manner that by one revolution of said shafts' always one box will becompleted. i

A A 4are themain frames of t-he machine.

BB are the driving-shafts, geared together by ,the wheels w wf, and.upon oneotsaid` shafts eitherpulleys arefto be placed to drive themachine by power or (as'h'ere represented in Fig. atlacrank C isattached to move the same by hand. y4 j D D' are rollers running inbearings in the frames A iA. These rollers are of such a size that theoutside circumference of the. same is equalto the length of thc paperrequired for one box. The lower rollers .D have' cranks ff attached tothe ends of their shafts, which are connected together by rods c e',thereby connectingal'l t-he lower rollers together, so that the samemove always simultaneously together.. The upper rollers `D.run loose inthe bearings inthe frames AA `and obtain their motion frointheircorresponding lower4 rollers by friction. I i

Near the front of the machine and as close as possible to theplace wherethe box is made are situated two sm aller rollers d d', moved by gearingv virom the nearest'roller D. l By, this arrangement the paper is alwaysheldl fast until the operation of folding begins.

, E is a stamp or knife frame situatedbetween two rollers near the.after end, guided` in the frames A A", and connected by links' e e tothe beams F F', from which the same I To the lower side of this frame Estamps or knives Areceives an up-andedown mot-ioni,

are attached, (shown in Fig. 2 in dotted lines) fitting, when presseddown, in suitable disks, by which said stamps or knives .the paper iscut or punched 'out the required shape inr4 the downward motion.lForward of the frame E, and likewise between two` rollers, thepasting-frame G is situated, guided, in

the frames A A', and connectedby links g` gio the beams F F', from whichthe saine receives an upand-down motion.` This pastingframe has suitableopenings a a to contain boxes filled with paste. The lower sides of,those boxes are covered with wire, flannel, lsponge, or its equivalent,so as to allow the paste to go-through in small quantities only, whichby pressing .down upon the paper is communicated tothe latter.

H isa wheel with four arms having at their extremities the moldshat'tached, round which the boxes are to be made., This wheel is Ifast hh h 7L are pins `attached 'to the wheel 7L, forming t'he` inner moldsfor 'the bases, fit

' between projections K IK', att-ached to the insidey of ,the frames AAf, and whiclrsaid projections/form ish/esides of the outer mold.

`lis ,a hinge-valve attached to the projeclattached to it to keep itclosed, and is likewise secured by the `catch L, fastened to the to ashaft running in bearings inthe frames if closedtowns the bottom ofprojection K'. .A spring la, acting against the `back of the catch L,keeps the same in'this position.

lns'tead of the weight d', attached to the valve l, a spring may be usedfor the/same purpose. y

M M are the top slides. N N' are thesidc slides. O is the lower slide,and O the upper slide, by which said slides the ends of the paper arefolded around the mold 7l. These slides are guided insnitable guides.

P are pinchers situated under the center of motion of the whecl'II andsliding up and down oversurfaces Q Q', attached to thcframes A A.Between t-he lower extremities of thc pinehers a spring 7c' is fixed toforce the same apart atthe required time.V On the upper end ofthepinehers are projections pp', which slide over the surfaces Q Q'. Thosesurfaces Q Q have elevations part of the way, and so situ-Y ated thatsaid pinchers P will be thereby pressed together in their downwardmotion, while at both extremities the same will be forced apart by theaction of their spring la. The reason of this arrangement is to ,give

clearance at the upper position for the mold h, with the finishedpaperbox'attached, to-

pass between the same, to keepthe paper box tight when" the same is tobe pulled olby the pinchers P from the mold 71. in the downward niotionof the pinchers, and to allow thebox to fall freely away from and ont ofthe pinchers Pafter having been .pulled oit from. the.

"F F are beams fast to a shaft b, turning in bearings in the frames AA'. To theforward end .'of those beams the upper slide O is attached,-aswell as the stamp or knife frame E and the pasting-frame G, as has' beenbefore described. These beams F F are connected, through the rods n n','with levers R R', turning upon centers'r 1r', fast to the frames A A',andv said levers 'R R are again con-f netzteil with levers S S', turningupon centers s s and which latter levers are acted upon by earns or toes1 'and 2, fast ion .the drivingshafts B B.- Through this connectionmotion communicated by the toes 1 and 2 to the levers S S' iscommunicated to the. beams F F', and consequently to thestam p or knifeframe `E, the pasting-frame G, and the upper slide 0', giving thereby anup-anddown motion'to those parts.

T T' arelevers` turning on centers tif', fasti,l

on the frames A A', and connectedgthrough the rods m m', with the crankson oneot'thel rollers D, by which. connection a rectilinearmotion,communicated to the levels T T', is,

converted into a circular motion of the :roll` c rs. These levers T T"are actuated bythe camsfortoes l3,1, 5,6,and 7., fas't on .the shafts-ll-, 'whichsaid cams ortoes are so' arranged kthat the motioncommunicated'by the salue. to .the one. cud offthelovers 'IT-T shallexactly produceon-o whole revolution of the rollers. vU is aleverturning uponithe shaft '(lhfast ver is attached to the lower slide O andthe other end is actuated by the cams or tocs'8.

.and 12 13, fast to the shafts'B l', and the other cnds of said leversare attached to belll cranks W \V', turningon centers 1' if', 'fast tothe frames A Al,'and connected with the lside slides N N', respectively.By this connection the action of' the cams 10 11 and 1f. 13 upon theends of the levers V V' produces a lat?- eral motion to'ithe slides N N.

X X' are levers turning upon-the shaft C, fast to .the frames A A. heone end of these levers is actuated by the cams or toes 1415 and 16 17,fast tothe shafts "B 13', and the other ends of said levers are attachedto bell- -cranks Y Y', turning en centers i i', fast to the frames A A',and connected with the top slides M" M', respectively. By thisconnection the action of the cams or toes 1 4 15 and 16 17 upon the endsof Ythe levers X X produces a lateral motion to the top slides M M.A

Z is a lever turningnpon the shaft q, fast to the frames A A'. 'lhe oneend of this lever is attached, through the links 6', with the pinchersP, and the other end isactedonbya cam 18, fast on the shaft B. This cam18 is sooonstrueted that by itsv action upon the lever Z the pine-hers Pwill 'be pulled down and retained for a certain time in thatposition,after which time and as soon as/the cani 18 sets the lever Z at libertythe pinchers P will be forced up again'by a springz, attached tothelever Z.

L' is a rod ru nningncarl y the whole length of the machine under therollers. The for- Ward 'end of the same is ent` out for -the pins 71,'of the wheel II to t in and is pressed against said pins, by the springo, acting against the underside of saidrod L'. -The same has vsuitable.guides at the forward end and is attached 'by means of a spiral springq.' at the after end to the frame A. On one side of t-hisrod L and nearthe forward end4 is'a small projection Fig. 3,'so situated as to operatewhen in motion, upon the catch L in such a 'manner as to liberate thehinge-valve I from its action. P' is aleve *turning upon a fixedcenterg,

fastto theframe'A.l 'lhe oneend of this lever actuated by the cam 1,9,fast on the shaft li.'

.By this connectionof the lever P with the ,rodjL'thc motioncommunicated to t-he lever 'P' bythe cam-1D produces a forward motion ofthe rod L,.and.tnrns thereby the wheel Il as soouas' said -rod L' comesin contact with oneA ofthe pins h', fast to the wheel ll. The cam 19 hastwo projections, which are so con structedl that the Vtirst projectionmoves the 'lever P. acertain distance and retai'ns'itin,44

about forty-fivel degrees.

thatposit'ion some length `of time, when the second projection begins toact, moving the lever P some distance farther, and likewise retains thesame in that position a certain vlength of time and then leaves thelever P'l `pulls` the rod L', as well'as the lever P', back again toitsformer and original position.

Instead of cutting or punching out the paper by the iabove-describedflat stamps the same may likewise bedone by attaching the knives to oueof the rollers D or D', andA the pasting-frame `may likewise be changedby substituting 'a ihollow roller with suitable openings, and into whichthe paste is forced.A

The spacell between the frames A and A' `and the lower rollers D isfilled Ain with plates H', whose upper surfaces come very nearly evenwith theupperpart of the circumference of thev rollers D, 'formingthereby a table over 'which the paper slides. l,

The operation of this machine is as follows: ln the accompanyingdrawings the' machine `.is represented in a-'position supposed that abox has just been completed. The cam 19 has already moved a little thelever P', and

consequently the rod L', and as this motion hasbeen just suicient forthe projectionaV i Vou the latter to have acted on the catch L, so

as to bring4 the same clear of the valve l, saidl valve I is now onlykept closed by its. weight a', and can be pressed open by the mold h toallow'the sameby the mot-ion of the wheel H to move outof'the'outermold. `By turning now at the handle G, settingthereby'themachine in motion, the cam 19 will still act upon the leverP', and consequently on-the rod -Lf, which comes now in contact with oneof the' pins h' of `the wheel H and turns `the same partly; around,'thereby bringing the inner mold h. (where we suppose a nished boxattached) clean of the outer mold, formed by the projections K and Kandthe valve I. VIn this'operation the valve I has been pressed downltoallow the mold h topass, and is then closedagain by its weight a', andthe catch' L, which has likewise been released ,from theprojection x ofthe rod L', is pressed by its spring k, so ya-,"to lock the valve Ilirnily to its place. The cam 19 moves the lever P', and consequentlythe rod L', so far that by the action of the latter against the piu 7L'of the wheel Il this wheel H' has turned so far around that its armsstand atY an angle of During. this time the cam 18 has acted continuallyon the leverr i Z, keeping the same, and consequently the pinchers P,steady and the latter inthe lowerV position. As soon as the arms of thewheel- Harrve at the above-described position-4 namely, at anangle` ofyabout forty-tiverdegrecs-the cam 18 relieves the lever Z from itsaction, and tliesame is no'w acted upon 4by vvthe spring z, therebyforcing the pinch' ers `P. suddenly upward. The pinchers are at this'topposition ,pressed apart by the action of their spring 7c', as abovedescribed, so. as to allow the arms or Imolds h of the wheel H to passwithin them. At the same ,tixne the above-mentioned operation has \beengoing on the toes 8, 4, 5,.6,`and 7 have acted alternately upon thelevers T and T', respectively, moving the same backward and forwardl,'and whichy motion has been commnn-icate, through the rods fm mi', tothe cranks ff' of one of the lower rollers D, prothe same, and as all'the lower rollers are connected ogether, and the circumference of each'roller is just equal to the length of pa@ of'papeil has by thisoperation been brought forward! As .will appearby the following, thereisin the table of the machine, formed by thep` ates H' and in thepositionthe ma-y .lying close to the forward en d of the machine, readycut and pasted for folding; close to and cut or stamped out, onlyrequiring to be the `paper drawn into the machine by the situated behindthe machine. By the operareadycut andipasted, isbrought now forward andpushed over the opening of the outer mold, resting upon the top slides Mand M', ready tobe folded, While the second piece of paper is broughtforward and into the place which was occupied before by the first piece,to be pasted by the next operation, and a further piece from the endlessroll of paper is pulled before by the second piece, to .be cut olf bythe stamp the required length and shape. The first projection of the cam19 has rought the arms of the wheel Hin the position above mentioned andkept the same statidnary in Vthat position until the motion of therollers, and consequently ot the paper, is completed.

upon the lever. P', and consequently on the rod L-, producing a furthermotioni of the wheel H suicient to bring the arm oilrinner l'mold h intothe outer mold,l, thereby;folding of said outer mold around itself andtaking it with it intov the same, leaving onlythose parts of the paperprojecting which are to form `the top andnend of the box. This cam 19keeps, tthen, the lever P', and consequently the rod' L' andfwheel H,for some little time stationary in that position-until one of the topslides the same is secured, when the cam 19 leaves the lever P', and thespring q' at the end of to itis original position :ready for the nextac'- tioul "".After the mold h hasvbeen moved dncilng thereby j ust onewhole revolution of per required to' make one box, such a length chineist ow in,.one required length of paper,

K KandA the Valve I the' toe Meets then upon the lever X, which lever byits connection, through the be1l-crank Y, with thetop slide M moves thelatter over the moldv h,

.folding thereby the projecting paper over the The toe l5 acts now uponlythe same will likewise be pasted together.y

.The toe l2 acts now upon the lever V', which by its connection, throughthe bell-crank XV", with the side slide Nfmoves the latter over the endof the mold h, folding thereby the projecting pieceof paper over thesame. The tool?) acts then upon the opposite side of the `lever V', andbrings thereby the side slide Nl away' again. W'hen the side slide N isabout half-way brought back again, the toe 9 acts upon the lever 'U,which by its connection with the lower'slide O brings the same upwardand over the end of the mold @and at the same time thletoes l act uponthe levers'S and S', which by their 'connect-ions, throughthe levers Rand R and the rods 'n and n', re spectively, with thev beams F and Ff,and the connection of the latter with the upper'slide 0'-, move thisupper slide downward and over the end lof the mold h. By those two lastop- @rations the top and bottom projecting pieces of paper have beenfolded over the end' of the ino'ldhand over the piece of paper which wasfolded before by the side slide N. The ,toes 2 act then upon theopposite sides of the levers Sand S- and the toe 8 upon the oppositesideot the lever U, bringing thereby the upper and lower slides Ol and Oback` again. During the return motion of --those slides the toe 1Q actsupon the lever V, which byits connection, through the bell-crank W, withthe side' slide N moves said sideslide over the end ofthe mold h,thereby folding the paper projecting ou that side over the end of themold and likewise over the three other pieces which have been' foldedbefore over 'the end of the mold 71 and .as this last-folded piecev o fpaper was pasted beforehand the same has by the lastmentioned operationof folding beenpasted to the other pieces of paper which were folded'first, The toe 11 acts then upon the opposite side of the lever'V,bringing thereby the slide' N back again, and the toe 17. acts upon thelever X', whereby the top slide M is broughtv back, and leaving theboxjnished, folded,j and pasted together on the .mold h'. During thetime thatthis operation 'offolding thegpaperal'ouudthe mold h has beengoingt'onithe cam 18 has acted on the lever Z, and, through theconnection-of the latter with the pinchers P, the same have been pulleddownward by the action of this cam 318 on said lever Z. In this downwardmotion of the pinehers P the projections p pf on the pinohe'rs P havepassed over the elevations on the slides Q Q", and have pressed thereby'the pine-hers P together, s o that the same take hold of the iinishedpaper box, which We have supposed to be on the lower mold h,andpullthereby said box off this mold h. As soon as the pinehers have beensufficiently far moved downward, so as to have pulled vo the paper boxclear `of the mold, the projections p p"leave the elevations on theslides Q Q, and the pinchers are then forced apart by the action oftheir springk',thereby allowing the boxY to fall out from between saidpinchers. .During the down ward motion of the beams F F' the knife orstamp frame E and the pasting-frame G have been pressed down and uponthe paper sit'- nated upon the ltable H and between the rollers D and D'and held stationary at that moment'by said rollers. By this action thestamps or knives attached to the under side of the frame Ecut ofia pieceof paper the required shape necessary forv one box, while the boxes withpaste, situated within the past ing-frame G, have (by being pressed uponthe paper) pasted that piece'of paper inthe required places which liesunderneathv the same and which was cut out by the former formerlycut-0Epiece of paper has been pasted in the required places preparatory forfolding the next time.'
